Unbreakable Linux Network APIs available

Unbreakable Linux Network APIs available

Aside from the uln_channel tool that we recently released, we are now also supporting a number of webservices on ULN. A handful of useful APIs are available. Below is a little simple python example that works out of the box on Oracle Linux 6 (when you have an account on ULN) and a description of the currently available APIs. Note that the python code is very simplistic... I know no exception handling, wasn't the point ;)...

APIs :

client.auth.login(username,password) returns sessionKey 
client.errata.listCves(sessionKey, advisory) returns cveList
client.errata.applicableToChannels(sessionKey, advisory) returns channelList
client.channel.software.listLatestPackages(sessionKey, channelLabel) returns packageList
client.channel.software.listErrata(sessionKey, channelLabel) returns errataList
client.packages.listProvidingErrata(sessionKey, pid) returns errataList
client.channel.listSoftwareChannels(sessionKey) returns channelList
client.channel.software.listAllPackages(sessionKey, channelLabel) returns packageList
client.errata.listPackages(sessionKey, advisory) returns packageList
client.errata.getDetails(sessionKey, advisory) returns errataDetail
client.channel.software.getDetails(sessionKey, channelLabel) returns channelDetail
client.packages.getDetails(sessionKey, pid) returns packageDetail
client.auth.logout(sessionKey) returns retval

sample output of the code :
$ ./sample.py
Login : client.auth.login(username,password) returns sessionKey
Logged in...
List CVEs for a particular advisory : client.errata.listCves(sessionKey, advisory) returns cveList
Example : CVEs for advisory 'ELSA-2013-1100' : ['CVE-2013-2231']
List channels applicable to advisory : client.errata.applicableToChannels(sessionKey, advisory) returns channelList Example : Channels applicable to advisory 'ELSA-2013-1100' : [{'channel_name': 'Oracle Linux 6 Latest (i386)', 'channel_label': 'ol6_i386_latest', 'parent_channel_id': ' ', 'channel_id': 941}, {'channel_name': 'Oracle Linux 6 Latest (x86_64)', 'channel_label': 'ol6_x86_64_latest', 'parent_channel_id': ' ', 'channel_id': 944}, {'channel_name': 'Oracle Linux 6 Update 4 Patch (i386)', 'channel_label': 'ol6_u4_i386_patch', 'parent_channel_id': ' ', 'channel_id': 1642}, {'channel_name': 'Oracle Linux 6 Update 4 Patch (x86_64)', 'channel_label': 'ol6_u4_x86_64_patch', 'parent_channel_id': ' ', 'channel_id': 1644}]
List latest packages in a given channel : client.channel.software.listLatestPackages(sessionKey, channelLabel) returns packageList Example : Packages for channel 'ol6_x86_64_latest' returns 6801 packages
List errata in a given channel : client.channel.software.listErrata(sessionKey, channelLabel) returns errataList Example : Errata in channel 'ol6_x86_64_latest' returns 1403 errata
List errata for a given package : client.packages.listProvidingErrata(sessionKey, pid) returns errataList Example :
[{'errata_update_date': '2011-06-08 00:00:00', 'errata_advisory_type': 'Security Advisory', 'errata_synopsis': 'subversion security update', 'errata_advisory': 'ELSA-2011-0862', 'errata_last_modified_date': '2011-06-08 00:00:00', 'errata_issue_date': '2011-06-08 00:00:00'}]
List software channels available : client.channel.listSoftwareChannels(sessionKey) returns channelList Example : List of channels returns '253' channels
List all packages for a given channel : client.channel.software.listAllPackages(sessionKey, channelLabel) returns packageList Example : All packages for channel 'ol6_x86_64_latest' returns 25310 packages
List packages for a given advisory : client.errata.listPackages(sessionKey, advisory) returns packageList Example : Packages for advisory 'ELSA-2013-1100' returns 12 packages
Details for a specific advisory : client.errata.getDetails(sessionKey, advisory) returns errataDetail Example :
{'errata_update_date': '7/22/13', 'errata_topic': ' ', 'errata_type': 'Security Advisory', 'errata_severity': 'Important', 'errata_notes': ' ', 'errata_synopsis': 'qemu-kvm security update', 'errata_references': ' ', 'errata_last_modified_date': '2013-07-22 00:00:00', 'errata_issue_date': '7/22/13', 'errata_description': '[qemu-kvm-0.12.1.2-2.355.el6_4.6]\n- kvm-qga-cast-to-int-for-DWORD-type.patch [bz#980758]\n- kvm-qga-remove-undefined-behavior-in-ga_install_service.patch [bz#980758]\n- kvm-qga-diagnostic-output-should-go-to-stderr.patch [bz#980758]\n- kvm-qa_install_service-nest-error-paths-more-idiomatically.patch [bz#980758]\n- kvm-qga-escape-cmdline-args-when-registering-win32-service.patch [bz#980758]\n- Resolves: bz#980758\n (qemu-kvm: CVE-2013-2231 qemu: qemu-ga win32 service unquoted search path [rhel-6.4.z])'}
